I'm sorry if my english is not very good.
We often get an http 401 error when calling https://api-worldcheck.refinitiv.com/v2/cases/saveAndScreen, and sometimes we also get duplicates of caseID (but there is no duplicate call)
We use Spring batch and chunk management (sort of paging/batch).
We tested our treatments in parallel or not. In both cases, we get the same issues: 401 and duplicate case ID.
I can't give you an example query, because it's real data. But keep in mind that most work: so probably no authentication error.
Are there recommendations on the number of caseId in a call (50 max in the doc but is it correct), the number of calls, parallel or non-parallel... ? (my tests contain a hundred case to save, but in production, there could be more)
